gianni is married to scorrelli and they just had a little girl named gianna together. he has a daughter named bella with his ex girlfriend bgarcia and he has two kids with alannah which are actually just sperm donation babies but he plays the role of favorite uncle to them.
he is bisexual and dresses in drag. he's had several in game boyfriends as well as girlfriends. he is the only one with blue eyes and is supposed to look just like their grandfather but i'm not sure which side.
he hates their dad with a passion. i think that's the biggest thing about the family is that they all really dislike their dad but some far more than others.
